WPF DataGrid列宽和重新排序

我有一个DataGrid定义为

<wpftoolkit:DataGrid
        x:Name="AccountsDataGrid"
        AutoGenerateColumns="False"
        ItemsSource="{Binding Path=Accounts}"
        ColumnReordered="DataGrid_ColumnReordered"
        SelectionUnit="FullRow"
        RowHeaderWidth="0"
        HorizontalAlignment="Stretch"
        VerticalAlignment="Stretch"
        >
        <wpftoolkit:DataGrid.Columns>
            <wpftoolkit:DataGridTextColumn Header="Account Id" Binding="{Binding Path=AccountId}" Width="Auto" />
            <wpftoolkit:DataGridTextColumn Header="Account Name" Binding="{Binding Path=AccountName}" Width="*" />
        </wpftoolkit:DataGrid.Columns>
    </wpftoolkit:DataGrid>

是否有更好的方法来处理列宽，以及为什么列重新排序会破坏列的大小调整功能

列在columns集合中的位置不变。只有显示索引在更改。试试这个：

  private void DataGrid_ColumnReordered(object sender, DataGridColumnEventArgs e)
    {
        int lastColumnOrder = AccountsDataGrid.Columns.Count() - 1;
        foreach (DataGridColumn column in AccountsDataGrid.Columns)
        {
            if (column.DisplayIndex == lastColumnOrder)
            {
                column.Width = new DataGridLength(1.0, DataGridLengthUnitType.Star);
            }
            else
            {
                column.Width = new DataGridLength(1.0, DataGridLengthUnitType.Auto);
            }
        } 
    }

  private void DataGrid_ColumnReordered(object sender, DataGridColumnEventArgs e)
    {
        int lastColumnOrder = AccountsDataGrid.Columns.Count() - 1;
        foreach (DataGridColumn column in AccountsDataGrid.Columns)
        {
            if (column.DisplayIndex == lastColumnOrder)
            {
                column.Width = new DataGridLength(1.0, DataGridLengthUnitType.Star);
            }
            else
            {
                column.Width = new DataGridLength(1.0, DataGridLengthUnitType.Auto);
            }
        } 
    }
